From Sun to Roof to Grid: The Economics and Policy of Distributed Photovoltaics explores the benefits, challenges, and risks of DPV, with special attention to the economics of its deployment and its uses for utilities. The challenges addressed include inadequate electricity supply, energy access for low-income groups, natural disasters, decarbonizing the grid, and supply diversification. The report also offers a new paradigm to design policy packages for systems with more decentralized generation. In the new paradigm, DPV facilities can be better promoted by aligning the incentives of various stakeholders and distributing costs and benefits in a fair and efficient manner. The report also discusses the risks of DPV technology, and the means of mitigating them. Finally, it offers a comprehensive analysis of the benefits and advantages of DPV technology.
